SAW-FlLlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 327,774, dated October 6,1885.

(No model.)

the following is a specification.

This invention relates to an adjustable device intended for application to a sawelamp, or its equivalent, for the purpose of properly holding and guiding the tile during the operation of filing the saw.

The invention consists in the peculiar construction and combination of clamps and guides, as hereinafter described and claimed.

Figure l represents a perspective view of niy device. Fig. 2 is a vertical cross-section of the same. Fig. 3 is a cross section on the line x x of Fig. 2.

Referring to the drawings, A represents a horizontal bar designed to be attached to the side of a sawclamp or vise or other mechanism for holding a saw by means of studs a, or in any other appropriate manner. On this bar there is mounted a sliding clamp, B, provided with a thu1nb-screw, O, by which it` may be secured in position. The clamp is formed with an upright neck or socket to receive the vertical pivot or journal of a swiveling block, D, which may be secured in position by the thumb-screw E, inserted through the side of the neck to bear upon the journal.

To the side of the swiveling block I connect, by a horizontal pivot screw, F, as represented in Figs. l and 3, a tube or sleeve, G, which stands usually in a horizontal or substantially horizontal position.

Through the sleeve G there extends a round rod, H, which is free to turn and slide therein, and to one end of this rod there is secured a laterally-extending arm, I, attaehedrmly thereto and constituting in effect a part thereof, which carries at its outer extremity a lileholding handle or socket, J, which is united thereto by a vertical pivot, I). This handle or file-holder may be of any appropriate form adapted to receive and hold iirmly the tang or end of a vertical ile. The pivot b admits .of the file being swung horizontally, so as to bring its longitudinal operative faces parallel with the guiderod H, or at a greater or less divergence, according as it is desired to have the tile cut to a greater or less depth at each stroke. For the purpose of effecting this adjustment of the file with reference to the guide-bar, a screwrod, K, is pivoted to the file-holder and extended through the arm I, and provided with adj Listing-nuts L.

In operating my device the saw is placed in position in the clamp or vise, as shown at M, the guide-rod H turned until it crosses the edge of the saw at the desired angle, and viastened in position by tightening the screw E. The sleeve G is then adjusted on its pivot to give the tile more or less inclination from the horizontal and secured by tightening the screw F. As the rod is free to turn in the sleeve as well as slide therein, the file may be reciprocated across the saw, and urged downward with any required degree of pressure.

The movement of the file from tooth to tooth .is effected by the movement of the slide G upon the bar H.

Having thus described my invention, what I claim isl. In combination with a fixed guide, G, the reciprocating rod H, having the offsetarm at its end, the tile-holder jointed to said arm, and the adj listing-screw K, whereby the axis of the file may be adj usted with reference to that of the rod.

2. The bar A, and sliding clamp B, in combination with the vertically-swiveled block D and its clamping-screw, the horizontally-swiveled sleeve and its clamping-screw, and the sliding rod having the lateral arm with the file-holder attached thereto.

3. In a saw-tiling device, the combination of the guide-bar A, the slide B, the sleeve G, united to the slide by horizontal and vertical pivots, and the sliding rod H, connected to a file-holder attached to a lateral arm.

4L. In a saw filing device, a round rod arranged so that it may be reciprocated and rotated in a fixed guide, in combination with a tile-holder united thereto by an adjustable connection, substantially as described, adapt.- ed to permit the longitudinal axis of the tile to be adjusted parallel with or with a divergence from the axis of the rod.

In testimony whereof I have hereunto set my hand, this 1st day of April, 1885, in the presence of two attesting witnesses.
